I n I REINFORCED-CONCRETE POLE.

w whom it may ooncem 92:139.: :itknown that I, HARRY S. S'roU'r, a citizen; of the United States, and a resident of Geredo, in the county of Wayne and State o-ftWest Virginia, have invented a new and Improved Reinforced- Concrete Pole, of which the following is a full, clear, and exact description. The invention relates to reinforced concr'ete poles, andhas reference more particuliarly to the class comprising a metallic body covered with concrete.

7 7 An object of the invention is to provide an inexpensive reinforced concrete pole having a high co-et'ficiency of resistance to bend-.

ing stresses, and isufiicient resiliency to withstand shocks and to form a pole of uniform strength. 1

Reference is to be had to the accompanying drawings forming a part Ofthis specification, in which similar charactersofreference indicate corresponding parts in all the views:

- Figure is a vertical section through the concrete, of an embodiment of my'i'nvention, arts] in elevation; 2 IS an elevation o t e central reinforc- 'in'grmember; and Fig. 3 is a section on the line -r3- of Fig. 1, with a tear in the lateralsarfac of the pole to show the way the horizo'ntal reinforcing members are interconi fi3efore proceeding to a more detailed description of my invention, it must nder- 'thatithe cross section of the po e may 1 be i "ula r or polygonal. The central tubular -"renifor' cing member may be filled also with ebndrete, and the exterior appearance of the pole may be varied in accordance with individual preference orspecial conditions, without de rting from the underlying spirit of thg i ngreiition.

wInLthe appe ded vdrawings, 10 is the vertical itubuifinii'oentral member, preferably cir- -"cu'lzi;r in ros's section, and on its exterior lziteral s urfac'e provided with a plurality of longitudinal ribs 11 parallel to the elements fdi i'riirig; the-lateral surface, the ribs belng equally distributed on the surface, and their numbervpreferably corresponding to the number of sides the pole is tohave. A series figs 12,.preferably formed from a round Specification of Letters Patent.

the pole the desired slope and to form; a pole of'uniform strength.

The rings 12 are maintained concentric with the tube 10 by means of wire members 13 engaging the orifice 14 in the rib 11 and having on each side of the rib wire, ortions 15 wound about the rings 12,-and tl ien continued-to the lower rin 12 and again wound about the same, with t e end portions 16 of interconnection between two consecutive rings by means of wire is to keep them apart at adesired distance from each other. The wire member 13 not only keeps the horizon: I tal rings 12 in a predetermined position, but also reinforcesthe structure. The-horizontal ring 12 is placed below the lower end of the central tubular member 10 for the purpose of giving to the base a greater surface strength. I Near the upper'end of the central tubular member 10 a bolt 17 projects through projecting end of the pole having'an anchor plate 18, and the other end being provided with threads and -.a nut 19 adapted to support a member 20 for insulator brackets;

lar member .0, horizontal rings 12 and wire members 13, is covered with concrete 21, and theshape of a hexagon is preferably given to the so-formed pole, the bolt 17 being an- 18. The edges of the polygon forming the pole are made to lie on the same radial line to add strength to the edges, particularly at the upper part of the pole','where it is most needed. 7

A pole constructed according to the above description .will not only beof uniform tubular member, its bending moment will the wire members 13. The purpose of this the lateral surface of the same, the shorter with the rings provided on the tube 10 sofas strength throughout,-but, due to its vertical the purpose of giving the lateralsurface of The so-formed skeleton of the central tubuchored in the concrete by means of the plate be gieatly increased, and the concrete houspole lfas the skeleton uniformly covered with concrete, the reinforcing parts being well distributedcirrythe body "of concrete. Having. thusr described my invention, I

;claim as new-and desire to secure by Letters Patent: I
